Time for Truth: Living Free in a World of Lies, Hype, and Spin by Os Guinness
I was introduced to Os Guinness' writings not long ago when someone showed me a few passages from Guinness' more recent "Prophetic Untimeliness: A Challenge to the Idol of Relevance". He is an incredible thinker with the guts to think beyond fashion to the natural extension of our ideals. He also makes me very nervous as he exposes the dirty little secret of pop culture ministry - that in pursuit of cool, it rarely maintains it's grip on conviction.
"Time for Truth" speaks to the dangers of post-modern thought - it being a mirror image of modernity and reflecting that in it's own mine fields.
I recommend reading it. Unless you're just content to grouse and think about how much better church will be when your generation is in control. If that's the case, just keep surfing. You have many to commiserate with, and most of them are blogging.
